@scottjenson While it is by no means zero, my experience is that the toxicity factor in the fediverse is a fraction of those on other platforms, with Bluesky running a distant second and X somewhat further out than Mars.
That's the killer feature, and I believe it's based on moderation by humans who care about the experience here. Our vulnerability is that those human moderators burn out; that good instances shut down for lack of funding. We're going to need to work out how that becomes sustainable, how we build a culture of donating to our instances when we have the means.
I think it's going to take some time to work that out, because it's a cultural concern, not a technological one. I also think we should be patient and continue to grow organically until we're past that point, or we'll just continue to burn out admins and see good instances shut down.
